'Application filed December 4, 1919. serial No. 342,421.

T 0 all lwhom t may con/cem.' n Be it known that I, FRED J KLINE, a c1t1- zen of the United States, and a resident of New York, in the county lNew .York and State of New York, have invented certain new and useful Improvements in Paper- Fasteners, of which the following is a speciication.

This invention relates to paper fasteners and particularly to tongued paper fasteners in which the tongues are passed through papers or documents and through holes in a retaining member or washer and then bent down on said member.`

The main object of the invention istolprovide improved means for guarding the bent down tongues, so that they shall not catch on other articles such as papers and the like, after they are lbent down on' the retaining member.

My improvements embody a member to cover the bent down tongues, particularly the ends of the same, and also embody suitable means to secure the covering member to the paper fastener. The covering memv ber is so arranged that its edges come close vto the said retaining member and prevent papers or other articles from catching between the two members. l

The means I prefer to employ for accomplishing theabove object are illustrated in Figure 1 is a plan of apaper fastener embodying my invention. Y

Fig. 3 is a transverse section on the lines 3 3 of Figs. 1 and 2.:

Like characters refer to like parts in all the figures of the drawing.

In Figs. v1, 2 and 3, I have illustrated my improved paper fastener applied to a file of papers, such as letters or documents, and indicated by the letter F. The said paper fastener comprises a member 2- having tongues 3 which are adapted to be pushed through thefile of papers F and to pro'ect on top of the same. A member whic I term a retaining member or washer, is indicated by the numeral 4, and is provided with holes or perforations 5. The said member 4 is placed on the ile with the tongues 3 passing through the holes 5 and the tongues 3 are then bent down as-indicated in Figs. 2 and 3. The member 4l is provided with means for securing a third member, which I'term a covering member,

Anysuitable meansv may be provided for securing the covering member 6 to the member 4, and a type of such means is-illustrated in Figs. 1, 2 and 3, consisting of four over' hangingprojections or lugs 9, one near .each

of the four corners of themember 4'.' Such lugs or projections are adapted to guide and hold the edges 10 of the covering member when it is placed in position as indicate lin Figs. 1 and 3. The covering memberis 1 placed in position by sliding it enidwise between and under the ends of thelugs or illustrated in Fig. 1. It will be seen in projections 9 until it comes to the-position Fig. 3 that the tongue 3 vis entirely covered the covering member 6 is flat on top at 11, and provided with a groove 12 vat the bottom in which the tongues 3 are held.

F langes 13 areA provided, one on each side, by means of which the covering member is guided and held in position in coperation With the means on the retaining member 4. In Figs. 4 and 5, the means I provide for holding the covering member consist of overhanging portions 14 of considerable length, and having a cross-section resembling that of the lugs of Fig. 3.

In Figs. 6 and 7 is illustrated a modiied form of the type of retaining member seen in Fig. 1. Sixv lugs 9 are provided, three on each side, one being placed atthe central part, so that when the covering member is in place, the fastener is materially stiffened.

In Figs. 8 and 9 the retaining member 4 is provided with ridges 15, one near each longitudinal edge, and in the inner parts of said ridges are the lugs or holding members 9. A plain flat strip 6', shown in detail in Figs. 14 and 15, is used as a covering member.

The plain iat covering strip 6 can be used with any of the other forms of retaining member when desired, if it is desired to reduce manufacturing costs. The form for most economical manufacture of those illustrated comprises the retaining member of Fig. 1 with the covering member of Figs.y

14 and 15. Fig. 16 is an end elevation of a type of covering strip which has been stiffened by forming a ridge 16 at the middle of the cross-section, and extended throughout or nearly throughout its length.

IVhat I claim is 1. The combination with a member embodying two spaced apart-tongues adapted to be pushed through papers, of a flat retaining member having two holes through which the tongues can be passedy andbent down flat on the retaining member and two pairs of sloping projections struck up.from the interior part of the retaining member and each having an overhanging portion toward the central part of the retaining member, and atongue-covering member adapted to slide under the overhanging portions of said projections and be held thereby and cover the tongue ends.

2. The combination with a member having two spaced apart tongues adapted to be pushed through papers, and a retaining member having two holes through which the tongues can be passed and bent down lat on said member, of a covering member for the tongue ends, and a plurality of oppositely-placed, sloping abutments on said retaining member between the two holes, struck up from the interior part of said member, and between which abutments the covering member can slide and be held, said members being arranged with a space be- .tween the retaining member and the covering member vin which the tongue ends can lie and be covered by the covering` member.

3. The combination with a member embodying two spaced apart tongues adapted to be pushed through papers, of a retaining member having two holes through which the tongues can be passed and bent down flat on the retaining member and two pairs of projections struck up Jfrom the interior part of the retaining member, one pair near each end, and a tongue-covering member adapted to be passed under and held by said projections with its side edges in contact with the upper surface of the retaining member.

4. The combination with a member having two spaced apart tongues adapted to be pushed through papers, and a retaining member having two holes through which the tongues can be passed and then bent down flat on said member, ofv a covering member having its upper surface curved transversely from its central part to its side edges, and a plurality of pairs of hooks on said retaining member, between the two holes therein, struck up from the interior part of Said member, and between which the covering member can slide endwise and be held, covering the tongue ends, with its side edges in contact with the upper surface of the retaining member.

Signed at New York City in the county of New York and State of New York this 1st day of December, A. D. 1919.
